“We are going to have a night time special caucus the evening of the 4th to accommodate those with religious restrictions,” said the official, speaking Thursday to the Chronicle on background.
That special caucus — the only night event planned in the state to accommodate religious voters – is tentatively set for the Adelson Educational Campus,a school founded by Adelson and his wife, with doors opening at 6 p.m, the official said.
Adelson, one of the world’s richest men, donated $5 million to Gingrich’s Super PAC, and his wife Miriam, has matched that donation. But as an active backer of causes related to Israel, he’s also an Orthodox Jew, who observes the Sabbath from sundown Friday to sundown Saturday.

The Feb. 4 caucuses for the rest of Nevada’s voters are scheduled Saturday in the daytime starting at 9 a.m., though they are expected to start a bit later in the northern part of the state.
But the Adelson caucus was scheduled because of the billionaire’s concerns about being unable to participate in the morning events, GOP insiders said.

The state party official said no other nighttime caucuses are planned in Nevada to accommodate religious voters, and deferred any other questions to a press call planned tomorrow morning to outline the caucus process and scheduling.
Meanwhile, officials in the campaigns of both former Massachusetts Gov. Mitt Romney and Texas Rep. Ron Paul are privately expressing concern about the decision. They raise a fairness issue — saying that a special evening caucus for Adelson could not only delay the results, but may open the party and the process to legal challenges.

Las Vegas is in Clark County, by far the state’s most populous county with 70 percent of its entire.
“I’ve been flooded today (with phone calls),” said one prominent Nevada Romney backer, speaking not for attribution. “What if someone has to work, or has a soccer game” and can’t attend the morning caucuses?
And there’s the question of whether the move shuts out religious voters — Jews and non-Jews alike — in other parts of the state who will be given no such accommodation, the Romney backer said.
The Romney backer said it appears party officials “are saying we want to help Sheldon — but others saying the rules were passed months ago and, billionaire or not, you can’t change them.”
“And you have people in Washoe County worried that if Clark does it, they’ll get sued for not doing it,” he said.
Insiders in the Ron Paul campaign, which has put volunteers and advertising resources into Nevada, are also preparing to raise concerns, Nevada Republican sources say.
Rumors have being flying around Nevada in recent days about the state party’s decision to accommodate Adelson with a special caucus.AP reported earlier this week that “the Clark County Republican Party said it will hold the evening caucus to accommodate roughly 500 conservative Jewish voters observing the traditional weekly day of worship. Most Nevada Republicans would still be requested to caucus from 9 a.m. to 3 p.m. on Feb. 4.
